Function Documentation

ad5628_init()

int32_t ad5628_init	(	struct ad5628_dev **	device,
		struct ad5628_init_param	init_param
	)

Initializes the communication peripheral and the initial Values for AD5628 Board and resets the device.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

ret - The result of the initialization procedure. Example: -1 - SPI peripheral was not initialized or the device is not present. 0 - SPI peripheral was initialized and the device is present.

ad5628_power_mode()

void ad5628_power_mode	(	struct ad5628_dev *	dev,
		uint8_t	pwr_mode,
		uint8_t	channel
	)

Sets the device in a specific power mode.

Parameters

dev	- The device structure.
pwr_mode	- power mode of the device. Example: AD5628_PWRDN_NONE AD5628_PWRDN_1K AD5628_PWRDN_100K AD5628_PWRDN_3STATE
channel	- The channel or channels that are being configured. Example: AD5628_ADDR_DAC_A AD5628_ADDR_DAC_B ... AD5628_ADDR_DAC_ALL

Returns

none.

ad5628_remove()

int32_t ad5628_remove

(

struct ad5628_dev *

dev

)

Free the resources allocated by ad5628_init().

Parameters

Returns

ret - The result of the remove procedure.

ad5628_reset()

void ad5628_reset

(

struct ad5628_dev *

dev

)

Resets the device.

Parameters

dev	- The device structure.

Returns

none.

ad5628_set_input_register()

void ad5628_set_input_register	(	struct ad5628_dev *	dev,
		uint32_t	register_value
	)

Writes a 32-bit data-word to the Input Register of the device.

Parameters

dev	- The device structure.
register_value	- Value of the register.

Returns
